Roman likes gambling, but Niko worries about him, because Roman gambles all his money, and gets into debt with loan sharks. His gambling addiction is why he got kidnapped by Johnny Klebitz (Roman got into serious debt with the Russians, and the Russians order Johnny to kidnap Roman so he can pay his debts, and another reason is because Ashley Butler owed Dimitri Rascalov a lot of money, and the Russians tell Johnny to kidnap Roman or they'll kill Ashley).
